The method or device or system can monitor and analyze the reaction process in real time and adjust the reaction raw material proportion and / or reaction conditions in real time.

Description

technical field [0001] The invention relates to the application field of microchemical technology, in particular to a continuous flow production control method, device and system of a microreactor. Background technique [0002] In recent years, microreactor technology, as an important technical means of chemical process intensification, has gradually become a hot spot in research and application. Around the core process of "three transmissions and one inversion" in chemical production, relying on the large reduction of characteristic size, microreactors are in the process of mass transfer. , heat transfer and other processes, the efficiency is increased by 10 to 100 times compared with conventional equipment. For some rapid reaction processes, microreactors have many advantages such as good safety, process controllability and direct scale-up. [0003] At present, for the reaction process controlled by heat and mass transfer, it is a main direction of the application of micr...

Problems solved by technology

However, for some production processes with relatively harsh reaction conditions, small changes in input conditions (such as flow, temperature, pressure fluctuations, etc.) fluctuate and cause instability of the output product

[0004] At present, the control of the microreactor system is often the monitoring and control of the flow, temperature, pressure and other inputs. In the case of continuous flow production operations, there is still a lack of detection and adjustment control means for product analysis and changes.
